y Specation af .Letters 'latent NO- 10,710, datedy March 28, 18,54.

To all whom Maag/maarre Be it known that I, THOMAS G. Suce, of` Jersey City, in the county 4of Hudson andl State of New Jersey, have invented certainy new and useful Improvements in Machines for Tenoning and Wiring or Prieking Blind- Slats; and l do herebydeclare that the following is a full, clear, yand exact description l of the construction and operation of the same, reference being had to .the annexed drawings, making a part of this specification, in which.-

Figure l, is a planer top view .of my improved machine. Fig. 2, is aside elevation of ditto, the side of the frame or bed nearest the eyebeing removed. Fig. 3,is a vface view of one of the cutter disks and the stationary knives; the stat-ionary knives are shown in;

red. Fig. 4c, is a detached view of a blind slat. lever, staple or pricking lever, and cam, by

`which the two levers abovementioned are presently shown, the tenons are perfectly cut-one at `each end of the slat, at the same v Ied, F-ig. 3.

time, and of an equal length.

This invention consists, 2d, in the-employ# ment or use of a clamp lever, and a staple or prickinglever, arranged and operating as. will be hereafter shown, whereby,'in case ofj the slats varying in width, an equal distance is always obtained between the tenons and the edge of the slat in which the staples fare driven. plained.

This will be hereafter fully ex- To enable others skilled inthe art, to make and use my invention, I will proceed to describe its construction and operation.

A, represents a frame or bed, on which two heads, B, B, work or vibrate, a head being on each end of the frame or bed, as shown in Figs. l and 2. On each head there is placed on suitable bearings, (a), a small Fig. 5, is a detached view of the yclampv or arbor, C, provided `withy a pulley,

D, and on the inner end of each shaft, Aor arbor, C, there is secured a `circular disk, E. .Each diskE, has three cutters, (b), (c), (d), secured to its face, as shown' more particularly in Fig. 3. Twovof the cutters, (In),

(0), are secured radially to the disk yat `opposite points upon it, the cuttersbeing a short ,dist-ance from the surface ofthe disk, as shown in Figs. l and 2, and secured to the ledges or sockets, (e), attached to the disk,

at its edge. .One .of the edges of eachv of the cutters, 1(1)), (c), is sharpened or beveled to `form a cutting edge, see Fig. 3, in which, (0), (o), representthe cutting edges of the' cutters, the'arrowk showing the' direction in 1 which the disk rotates. Theinnerends of `the cutters, (In), A(o), do not meet,fbut a space is left between, which is lequal to the diameter of lthe tenon to be cut, see Fig. 3.

The cutter, (d), is secured `to the faceof .v I

the disk, E, its inner end being somewhat rounded, andv forming a cutting edge, `as

shown'at .(o), FigQ. This cutting edge extends across, or to the center of the disk. The cutter, (cl-) ,pmay be placed radially upon the face ofthe --disk, or ratherk obliquely upon'it, as shown 'in Fig. 3. y

Each of the two disks and their cutters,

`(b), (c), (d),are,constructed precisely similar to each other. v

To -eaclihead, B, and l.directly infront of the disks, E, E, are attached stationary knives, F, F, one ,pairl of stationary knives bue-fore ,each disk. lThe lower knife, F,` is

fixed, orA is immovable; and its cutting edge is horizontal, and extends across the disk a short distance below its center, as shOWn in The upper knife, F", slides or works yon guides, ,(f), 4(f),directly over the lowerknife, F, and is therefore adjustable, andi/ts cutting edge maybe brought nearer to, vror farther from, the cuttingedge of the lowerknife, F. l,

1G, Figs. 1, 2, yand 5, yis a transverse sta-v tionary crossl pieceon the upper part of the f frame, or bed, A, and at about its center.

H, y,is a clamp lever, the 4fulcrum,.(g`), of which isk on the under side of the cross piece, asjshown in Fig. 5. Theupper part` of the clamp --lever passes -upward :through a v,slot in the cro-ss piece, and extends a short distance above the upper surfac'e of the cross piece. I, is a staple, or pricking lever, also havingV its fulcrumy on the under side of the crosspiece, at (It). The upper end of the cam, J, and shaft, K, are placed between the levers, H, I, the lower ends of the le` vers, H, I, by means of springs, (i), (i), bearing against the periphery of the cam, as shown in Fig. 5.

The two heads, B, B, areconnected to the vertical shaft, K, by means of rods, (j), (j), the rods being connected to theshaft at y opposite points upon its periphery, as

shown in Fig. 2.

On the upper surface of the cross piece, G, are two ledges or guide stops (la), (la), as shown in Figs. l and 2. The inner ends of these ledges or steps are at such a distance from the line ofv the centers of the two disks, E, E, as to correspond to the distance desired to be between the tenons of the blind slat and its inner edge. The ledges or stops are secured to the cross piece by set screws,

(l), (Z), and therefore may be adjusted as occaslon requires.

On the upper part of the staple or pricking lever, there is placed a dog,\L, one end of which, (in), is square, and the opposite end is vprovided with two points, (n),` (n).

M, is a lever attached to the lower part of the shaft, K. i Y

Operation: The blind slats are laid upon the cross piece, G, transversely, one at a time, the center of the slat being opposite the clamp lever, H, see Figs. 1 and 2, (p),

representing the slat. The upper stationary knives, F, are thenadjusted so as to allow the ends of the slat to pass between the knives, F, F', before each disk, E. The lever, M, is then moved'in a direction Vfrom left to right, and the cam, J, rst acts against the lower end of the clamp lever, H, and the upper part of the clamp bears against the outer edge of the slat, (p), and

forces it tightly against the ledges, or stops, (la), (7c).V The heads B, B, are then drawn inward or toward each other, in consequence of their attachment to the shaft, K, by

means of the rods, (j), (j), and the cam, J,

bears against the lower part ofthe staple, or pricking lever, I; the upper part of said lever, I, moving forward toward the inner edge of the slat, simultaneously with the movement of the heads, B, B. As the heads, B, B, are drawn inward, the cutters, (b), (c), on the disks, E, E, cut the tenons, the disks being madeto rotate by means of `belts passing around the pulleys, D, D. The

cutters, (d), (d), cut ofi' 'the ends of the tenons, so that they are made of an equal length. The stationary knives, F, F, prevent the shoulders of the slat from being broken by the action of the cutters, (b), The shoulders, therefore, are made perfectly smooth, as the stationary knives and the cutters operate similar to a pairof shears. When the upper part ofthe staple,

or pricking lever, I, moves forward, the

staple is forced intopthe inner edge of the slat, or the holes for the staple is pricked, either may be doneY as desired, if the square end (m), is toward the slat, the saple is forced into it, the staple being previously placed before the dog; but if the holes are to be pricked, the opposite ends., (n), @1.)

of the do-g are placed toward the slat, and.

the points .will enterV the slat and form the necesary holes. The dog, L, it will be seen, may be reversed upon the lever, I. When the lever, M, is released from `the hand, the

heads, B, B, return to their original position, by means of the springs, (r), (r), see Figs. 1 and 2, and the clamp and staple, or pricking lever, return to their original position, by means of the springs, (i), (71).

Blind vslats are wired in .two different ways, viz: by forcing the staples direct-ly into theslats, withoutholes, and by first` making holes, and driving the staples into them. Y. f 1

I am aware thatcutterasimilar to the ones, (c), herein-described, have been previously used on rotating disks for simi? lar purposes. I, therefore, do not claim the cutters (c), separately; but

Vhat I claim as new and desire to secure by ALetters Patent, is

L The employment or use of the stationary knives, F, F',v and the cutters, (b), (o) (d), arranged upon a rotary disk, E, the knives and disk with the cutters attached, being secured lto a vibrating head B. Two heads B, B, being employed on one machine,

Yand operating in the manner and for the purpose substantially as herein shown and described. l

2. I claim the employment or use of the clamp lever H, and staple or pricking lever, I, arranged and operating as herein shown and described, for the purpose of properly clamping t-he slat, and pricking the same, or driving the staple therein.
